The Sum Of Two Numbers Is 54 And Their Difference Is 16
The problem given says that 2 unknown numbers are given, whose sum is equal to 54 and the difference is 16. Let's find the two numbers :When we add the two numbers :
X + Y = 54
The difference of two numbers :
X - Y = 16
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 54 X - Y = 16 2X = 70 |
Let's divide 70 to 2 for the first number "X" .
X/2 = 35
First number is 35
X + Y = 54
So ;
35 + Y = 54
Y = 54 - 35
Y = 19
Second number is 19
